[stringtemplate-interest] [ST4 Beta-2] No whitespace allowed before <@end> when at new line

[Terence Parr]

made sure it accepts and also ignores indent in front of <@r> etc...

	@Test public void testIndentBeforeRegionIsIgnored() throws Exception {
		String dir = getRandomDir();
		String g = "a() ::= <<[\n" +
				   "  <@r>\n" +
				   "  foo\n" +
				   "  <@end>\n" +
				   "]>>\n";
		writeFile(dir, "g.stg", g);

		STGroupFile group = new STGroupFile(dir+"/g.stg");
		ST st = group.getInstanceOf("a");
		String expected = "[\n" +
						  "  foo\n" +
						  "]";
		String result = st.render();
		assertEquals(expected, result);
